Top 5 Open Source Linux Server Provisioning Software

Server provisioning is nothing but load the Linux or UNIX like operating systems automatically with actual operating systems, device drivers, data, and make a server ready for network operation without any user input. Typically you select a server from a pool of available servers, load the operating systems (such as RHEL, Fedora, FreeBSD, Debian), and finally customize storage, network (IP, gateway, bounding etc), drivers, applications, users etc. Using the following tools you can perform automated unattended operating system installation, configuration, set virtual machines and much more. These software can be used to install a lot (say thousands) of Linux and UNIX systems at the same time.

From the official Redhat guide:

Many system administrators would prefer to use an automated installation method to install Red Hat / CentOS / Fedora Linux on their machines. To answer this need, Red Hat created the kickstart installation method. Using kickstart, a system administrator can create a single file containing the answers to all the questions that would normally be asked during a typical Red Hat Linux installation. Kickstart provides a way for users to automate a Red Hat Enterprise Linux installation.

Kickstart Configurator allows you to create or modify a kickstart file using a graphical user interface, so that you do not have to remember the correct syntax of the file.

FAI is a non-interactive system to install, customize and manage Linux systems and software configurations on computers as well as virtual machines and chroot environments, from small networks to large-scale infrastructures and clusters. It is a tool for fully automatic installation of Debian and other Linux Distributions such as Suse, Redhat, Solaris via network, custom install cd, or into a chroot environment. Some people also use it to install Windows.

Cobbler is a Linux provisioning server that centralizes and simplifies control of services including DHCP, TFTP, and DNS for the purpose of performing network-based operating systems installs. It can be configured for PXE, reinstallations, and virtualized guests using Xen, KVM or VMware. Again it is mainly used by Redhat and friends, but you can configure a PXE server to boot various non-RPM boot images such as Knoppix and other flavors of Debian such as Ubuntu.

There is also a lightweight built-in configuration management system, as well as support for integrating with configuration management systems like Puppet. Cobbler has a command line interface, a web interface, and also several API access options.

From the official website:

Spacewalk is an open source (GPLv2) Linux systems management solution. It is the upstream community project from which the Red Hat Network Satellite product is derived. Spacewalk manages software content updates for Red Hat derived distributions such as Fedora, CentOS, and Scientific Linux, within your firewall. You can stage software content through different environments, managing the deployment of updates to systems and allowing you to view at which update level any given system is at across your deployment. A clean central web interface allows viewing of systems and their software update status, and initiating update actions.

openQRM is the next generation, open-source Data-center management platform. Its fully pluggable architecture focuses on automatic, rapid- and appliance-based deployment, monitoring, high-availability, cloud computing and especially on supporting and conforming multiple virtualization technologies. openQRM is a single-management console for the complete IT-infra structure and provides a well defined API which can be used to integrate third-party tools as additional plugins.

Complete separation of “hardware” (physical servers and virtual machines) from “software” (server-images)Support for different virtualization technologiesFully automatic Nagios configuration (single click) to monitor all systems and servicesHigh-availability : “N to 1″ fail-over Integrated storage managementDistribution support – openQRM 4.x comes with a solid support for different linux distribution like Debian, Ubuntu, CentOS and openSuse. A single openQRM server can manage the provisioning of servers from those different linux distributions seamlessly. Fig.04: OpenQRM Dashboard (image credit: OpenQRM project)

You can build your own server using PXE, TFTP server, and DHCP software. PXE allows you to boot up a system and have it automatically get an IP address via DHCP and start booting a kernel over the network. See the following articles for more information:

There are many proprietary software solutions available to automate the provisioning of servers, services and end-user devices from vendors such as BladeLogic, IBM, or HP. But open source software gives you more freedom to automate the installation of the Linux server. Some of the above software support UNIX and Windows operating systems too.
